6ix9ine has started his testimony against his one-time gang associates Anthony "Harv" Ellison and Aljermiah "Nuke" Mack, and during it, he reportedly mentioned Trippie Redd, a former collaborator-turned-rival.

According to reporter Matthew Russell Lee, who is live-tweeting from the courtroom at Manhattan's Thurgood Marshall United States Courthouse on Tuesday (Sept. 17), 6ix9ine alleged that Trippie was once a member of a gang.

"Trippie Redd was part of Five Nine Brims, Hernandez testifies," writes Lee, who refers to Tekashi by his government name of Daniel Hernandez.

That bit of Lee's report arrived in the midst of Tekashi's testimony, which has thus far recounted the birth of his connection to the Brooklyn-based gang, Nine Trey Gangsta Bloods and more.

For his testimony, which has been speculated about for weeks now, the rapper is expected to discuss allegedly being kidnapped by Ellison and both Ellison and Mack's alleged gang activity. He is also expected to testify that his role in the Nine Trey gang was to "make money for the gang and distribute that money among Nine Trey members."

6ix9ine is taking the stand in court, but it is unknown whether his family members are present. According to previous reports, the rapper's family was not planning to show up for the testimony in court because they feared for their lives.

XXL has reached out to Trippie Redd's camp for comment.
